Privatization of Social Security: Lessons from Chile

Peter Diamond

Abstract

In Chile, all covered workers must save 10% of monthly earnings wilh a highly regulated intermediary Ihat monages a single fund and provides survivors and disability insurance. Workers pay a commission charge, in addition to the mandatory 10%, to finance this insurance and to cover the costs and profits of the intermediaries. On becoming eligible to receive benefits, a worker can choose between a sequence of phased withdrawals and a real annuity. In addition, there is a sizable guaranteed minimum pension. Unlike the purchased annuities, the minimum pension is not indexed, but adjusted by Ihe government from time to time. The Chilean reform gets high marks for defending the system from polilical risk and for its effects on capital accumulation and on the functioning of the capital markel. The Chilean reform gets low marks for the provision of insurance and for administrative cost. Perhaps the most surprising aspect of the Chilean reform is the high cost of running a privatized social security system, higher than the "inefficient" system thal it replaced. Valdes-Prieto has estimated that the average administrative charge per effective affiliate while active is 2.94% of average taxable earnings. This is close to 30% of the 10% mandatory saving rate. The cost per person is not far from costs observed in older privately-managed pension systems. However, it is higher than administrative cost in well-run unified government-managed systems. The issue here is the administrative efficiency of the primte markel, not anything particularly costly about the Chilean system.
